Supply Diamond drill rig with axle, turnstile, allen key and operating instruction in a cardboard box. Application for Indented Purpose The diamond drill rig BST 352 V is made for diamond core drills which are fixed by means of a mounting plate (e.g.: EBM 352). The max. drilling diameter must not exceed 352 mm. When drilling overhead, a water collecting device must be used. In case of wrong handling or misuse, the producer does not assume any liability. Use

After each new adjustment, check that the screws are tight so that the drill stand can be used safely.15 Attaching the feed lever

• Attach the turnstile (1) to the left or right of the carriage (2). This depends on the work to be carried out.

• Please check that the turnstile (1) is correctly positioned.

Fastening of the Drill Rig Hole centering indicator: The drill rig is fitted with a hole centering indicator for easy and precise posi- tioning.

Fastening with dowels in concrete To fasten the drill stand with dowels, it is necessary to remove the vacuum grip and the foot seal from the base plate.

• Mark the position of the mounting hole on the surface to be drilled.

• Drill the hole (Ø 16) 50 mm deep (A) into which the M12 dowel (B) is to be inser- ted; insert the dowel and expand it with the dowel setting tool (C).

• Screw the quick-release screw (D) into the dowel.

Masonry anchors must be used for masonry.

• Secure the washer (E) and finally the fastening nut (F) on the quick-release screw (D).

• Tighten the nut (F) with a 27 mm wrench.

• Before and after tightening the nut (F), adjust the 4 adjustment screws as ne- cessary to adapt to the surface.

Be sure to check that the stand is securely mounted.

Vacuum attachment to the floor Do not use the vacuum attachment on walls or overhead! For vacuum mounting, the surface to be drilled must not be porous and must be flat and free of cracks. If this is not the case, this type of mounting cannot be used. For vacuum mounting, you will need a vacuum pump, the vacuum hose and the vacuum set BST 352 V (see fig.). These are available on request.

Assembling the vacuum set: Position the connection plate of the vacuum set on the drill stand base as shown. Turn the switch knob to lock the connection plate in the base. Check that the connection plate is correctly sea- ted. Place the foam rubber seal in the groove on the underside of the base.17 Please note that the levelling screws are adjusted so that they do not protrude from the underside of the drill stand base, as this will affect the vacuum and the stand may come loose from the surface. When using vacuum mounting, ensure that the vacuum is sufficiently high (min. – 0.8 bar). Make sure that the seals are not worn. Connect the drill stand and the vacuum pump using the vacuum hose. Move the drill stand into the correct position, open the ball valve on the con- nection plate and switch on the pump. The vacuum pump must continue to run throughout the entire working time and must be positioned so that you can see the pressure gauge. Be sure to check that it is securely fastened before you start drilling!

To release the vacuum attachment, close the ball valve. This opens a vent valve through which the vacuum can escape. This allows the stand to be moved while the vacuum pump is running, if necessary.

Fastening with quick-release column To brace the drill stand using the quick-release column, the distance to the opposite wall must be between 1.7 m and 3 m.

Position the drill stand. Place the quick-release column as close as possible behind the column on the stand base. Secure the drill stand by turning the crank (G) clo- ckwise. Secure the setting with the corresponding bolt (H).

Caution! It is important that the drill stand is firmly secured to the ground. Incor- rectly secured drill stands can cause injury to the operator and damage to the drilling unit. Movement during drilling causes the drill bit to strike the borehole wall, which can lead to the segments breaking off. The drill bit can also become jammed in the borehole, causing damage to it.

Fixing the Core Drill Motor18

Caution! When mounting the machine, risk of squashing. Wear protective gloves!

Assembly of the machine plate

Move the machine holder upwards until it locks into place. Use the feed lever to open the mounting plate lock. Remove it and connect it to the core drilling machine as described below. The scope of delivery includes a mounting plate, a 10 mm key and 4 M8 x 25 hexagon socket screws. The mounting plate is placed on the machine with the key so that the bushings in the mounting plate are on the same side as the gear shift of the machine. Then insert the four screws and tighten them securely. Insert the core drilling machine with the mounted plate into the drill stand and lock it in place using the feed lever.

For the operation of the core drill, its operating instruc- tions and safety advices have to be strictly observed!

To unlock the carriage (1), pull out the locking button (2). To lock the carriage, move it until the lo- cking shaft passes through the hole in the column and locks into place. Always lock the carriage when the as- sembly is not in use.19 Operations In order to operate the tool safely, please observe the following notes: Details of the work area

• Keep the work area free of everything which could obstruct operations.

• Provide for adequate illumination of the work area.

• Adhere to the regulations concerning the power connection.

• Lay the power cable in such a way that any damage by the drill can be avoided.

• Make sure to always keep the work area in view and to be able to reach all necessary operating elements and safety installations.

• Keep other persons away from your work area in order to avoid accidents. Space requirements for operating and maintenance Whenever possible, keep a free space for operating and maintenance of about 2 m around the drill position, so that you can work safely and have immediate access in case of a failure. Drilling At the beginning, drill very slowly, since the drill bit does only starts cutting with a fraction of the cut surface in the material. If you drill too fast or with too much pressure, the drill bit could get jammed. Angled drilling

• Remove the screw (1) that locks the column at 90°.

• If necessary, loosen the two screws (2) on the side of the base plate.

• Use the feed lever to release the lock (3) on the support.

• Now swivel the column to the desired angle. The scale on the tooth column makes it easier for you to set the drilling angle.

Drilling with Water20

If you are cooling the drill bit with water a water collection ring is recommended. This will be mounted with a latch fastener on the screws of the base plate and ensures a clean drilling. Mainly for overhead or lateral drilling. (see spezial- accessories). Demounting the Core Drill Unit

• Move the machine holder with the core drill upwards until it locks in the final top position.

• Remove the drill bit.

• Loosen the locking of the mounting plate and remove the core drill ma- chine from the drill rig

• Loosen the fastening nut (F)

• While doing so, hold the drill rig firmly!

• Remove the drill rig.

• Unscrew the quick action clamping screw (D) Care and Maintenance

• Always keep the drill rig clean, especially the column with the toothing and the 4 sliding balls in the machine holder. In order to allow the free movement of the pinion shaft, it should be slightly lubricated.

• In order to achieve a good performance of the drill rig, the 4 sliding balls in the machine holder have to move along the column without slackness. Attention! After every tenth drilling you should check if the sliding pieces have got loose-fitting due to drilling vibration. If the position should have changed, it can be readjusted as follows:

• Use a SW 17 open-end wrench to loosen the lock nut on the hexagon socket screw.

• Use an 8 mm hexagon key to adjust the hexagon socket screws and thus the po- sition of the ball bearings relative to the column.

• Tighten the lock nut again and check that the machine holder moves smoothly on the guide column of the diamond drill stand.21 Behavior by Malfunction

Turn off the machine by malfunction and disconnect from the electricity network. Operations on the electrical system of the machine can be executed only by a specialist.

Trouble Shooting Error Possible cause Solution Drilling unit has play (vibration) The stand has become loose. Tighten wing nut Lead has too much play Adjust guide Sliding balls worn Replace slide balls
